(2)頻度副詞在句中的位置
1)表示不確切頻率的副詞通常是用在句中的。而其在句中的確切位置,還與句中的動詞形式有關。具體來說有以下幾種情況:
①用在實義動詞之前,be(am,is,are,was,were)動詞和助動詞(will,should,have)之后。
a. I often do some shopping on weekends.
b. She is often late for school.
c. I have never seen him since we parted. 自從分別后我就再沒見過他。
②若句中的謂語動詞由多個部分組成,比如:will be done,should have done等,這時副詞一般要放在第一個助動詞之后。例如:
a. This project will never be finished.
b. You should never have trusted him. 你永遠都不應該相信他。
③在加強語氣的句子中,我們一般是把副詞放在第一個助動詞之前或be動詞之前。例如:
a. You really will get a reward one day. 總有一天你會遭到報應的。
b. —As a teacher, you should always be patient with students.
—I always have been patient.
④在只有助動詞而省去了實義動詞的句子中,副詞一定要放在這個助動詞之前。例如:
a. —You should have known better than to trust him.
你早就應該知道他這個人靠不住。
—I never will. (省去了trust him)我今后再也不會相信他了。
b. —Can you find a place to park your car in the street?
—Yes, I usually can.
c. Plenty of teenagers with computer skills are skipping school, or at least deferring for a few years. But while some kids have found decent incomes without college, most never will.
很多具有電腦技術的青少年輟學或休學了,盡管有些孩子離開學校后找到了收入不菲的工作,但大多數(shù)永遠不會。
副詞也要用在省略了表語的be動詞之前。
—I hear that his American girlfriend used to be his English teacher. 我聽說他的美國女友曾是他的英語老師。
—No, she never was. 不,她從來不曾是。
2)表示確切頻率的副詞一般只能用于句末。例如:
a. Milk is delivered daily. 牛奶每天都送來。
不說:Milk is daily delivered.*
b. We have meetings twice a week.
比較:We often have meetings.
c. They will be paid yearly.
3)上述表示不確切頻率的副詞,有些也可以用于句首或句末。例如:
Often/Sometimes/Usually I work late into the night.
我常常/有時/通常工作到深夜。
often一般不單獨放在句末,而須加very或quite修飾。例如:
a. He comes late for school quite often.
b. Often he comes late for school.
c. He often comes late for school.
4)always可在句末,但不能放在句首,除非用在祈使句中。例如:
a. You always make the same mistakes.
b. You make the same mistakes always.
不說:Always you make the same mistakes.*
但在祈使句中,我們說:
Always remember not to argue with your boss.
5)在否定句中的頻度副詞
在否定句中,有的頻度副詞位于not之前,有的頻度副詞位于not之后。這主要是從意思上來判斷。一般來說,always要放在not之后(not always);而often,sometimes,usually要放在not之前。例如:
a. He doesn't always leave before 6 o'clock, sometimes he works until 8 o'clock. (不總是)
b. His wife complains that he sometimes doesn't listen to her.?。ㄓ袝r不)
c. The history lectures sometimes aren't interesting.
歷史課有時很沒勁。
不說:...he doesn't sometimes listen to her.*
...aren't sometimes interesting.*
6)否定頻度副詞never,rarely,seldom有兩點須注意:
①不能再與否定詞not連用。例如:
不說:He doesn't seldom go out at night.*
應說:He seldom goes out at night. 他晚上很少出門。
②一般只用在句中。若放在句首,則句子要用部分倒裝。例如:
a. I have never heard such a story. 我從來沒聽說過這樣的故事。
b. Never have I heard such a story.
總的來說,對于頻度副詞在句中所使用的位置,我們應注意以下幾點:
1.表示不確切頻率的副詞通常用在句中,其在句中的具體位置又與句子的謂語動詞形式有關。
2.表示確切頻率的副詞一般只用在句末。
3.要注意否定詞與頻度副詞連用的位置關系。
